Disenchant value

[usiris]

First, im going to apologize if this is already a feature, but I did do not see it at the moment


Would it be possible to get the disenchant value of an item along side the price it is to make and sell?

For example I'm looking at enchanted thorium blades right now wondering if it is worth it to make and de.


The algorithm would look something like:
Get Ilvl of item
See if it is a weapon or armor piece
Get all possible items it can DE into
Get percentages it can DE into above items
(not sure about this)Output percentage gold

I would think the last part would be similar to getting the prospect value, but not entirely sure.



Thank you

That's a cool idea. It opens up a potential new area similar to the "Deals" page. You would really want to see min and max DE values, taking into account whether or not you have access to Bountiful Bags.

Sorry for my late response to this thread; I've been busy on another project.

Also, I recognize your name; thanks for your frequent mentions of TUJ on MMO-Champ.

I always wanted to do something with disenchanting with the site, for the longest time. Your idea is a good place to start. Of course, the tricky part is here:

Get all possible items it can DE into
Get percentages it can DE into above items

Got an algorithm or source for this?

I don't think Blizzard provides disenchant table data explicitly. In a general sense we can infer what it likely is based on ilvl and what other items of that ilvl have disenchanted into, but to know for certain user data would have to be collected. For example of inconsistencies in table data carnelian spikes celestial essence portion of the table did not benefit from bountiful bag bonuses until 4.3, however just from inference we would expect it to, which lead to significant differences in its actual values. In general though I believe that armors are 75% dust, 25% essences and weapons are the reverse. However, there are some % allocated for disenchanting into some shard type and either a small or large version that is seen in earlier content items when disenchanted, so it would be necessary to account for this somehow. There may be a general relationship known for that as to what % and of what ilvls that is restricted to. As a loose start the 75/25 trend could be used, ignoring the low % (1% usually) chance of small/large shard and assuming bountiful bags benefits that table equally.

This is where I got TSM's disenchanting percentages from:

Disenchanting tables - WoWWiki - Your guide to the World of Warcraft

The ones used in this spreadsheet: DE Spreadsheet were extracted from the enchantrix module of the auctioneer suite, before anyone had any access to Bountiful Bags (FWIW)

Got an algorithm or source for this?

This is my quick attempt at starting an algorithm for it:

Modify the code you used for the jc part; the value of one ore.
Since you had to use different percentages for rare vs uncommon, and even different gems that hold a much more significant value, you could modify that to the percent an item could be DE'd into and each item that can be produced from said item(using sapu's source or kath's)

If we cant do that(above) I can take a look at the shuffle sheet to find the algorithm they used for the rare vs uncommon, and I could prolly build off of that.

DE value or at least most probable DE results would be very nice to have.

I know only a bit about programing and a bit more about math, couldn't you construct a reasonable "worst-case" scenario for Disenchant-able items?

Using DE probabilities from wowhead or something, or even just the general 75/25 rules discussed above for greens, then assume the baseline DE result (we know that DEing a Jade ring will give is at least 1 dust if dust, and at least one lesser essence if lesser essence) then multiply by last-known price for the DE results, then do a weighted average and output that value as the base DE value? Similar for blue items, above whatever it is, ilvl333, they are going to give you AT LEAST one small shard, or two.

This conservative estimate method is how i have my own personal spreadsheets set up, and it gives me a wonderfully fast way of knowing if something is only marginally worth it or is definitely going to be worth it.

I knew I thought about this before.. Check this thread. I got so far into working with the stats from Wowpedia, then gave up because they are incomplete for Cata. It seems that Wowwiki now has newer stats that include Cata items.

Are we confident in those Wowwiki stats? I prefer that style (groups of iLvl) over the Wowhead item stats because I can generalize them and I don't have to rip them from shoddy observations.

I'm not convinced that the stats from Enchantrix are worth it, because where did they get their data?

[calianna]

Enchantrix is player data, I believe. I think the wowwiki/wowpedia stats would be good. As with anything, I'm sure there will be some random items that are broken or not following the rules in some way (like carnelian spikes for a long time).
